Shell minute, subfusiform, white, extremely variable, with a smooth blunt nucleus of a whorl and a half and somewhat less than three subsequent whorls; suture distinct, not appressed; whorls rounded; axial sculpture of slightly flexuous narrow riblets, usually with wider interspaces, varying from none at all to 24 on the last whorl, crossed by numerous fine spiral threads, equal and closely spaced over the whole shell, strong in some specimens, obsolete and barely perceptible in others, not anywhere nodulous; aperture subovate, outer lip nearly straight, hardly thickened, smooth within; body with a thin layer of enamel; pillar short, canal very short, axis pervious. Length of shell, 4; of aperture, 2; diameter, 2 mm. U. S. Nat. Mus. Cat. No. 108205. Off Fernandina, abundant.
The ribs are threadlike, sometimes almost like elevated lines and sometimes hardly more prominent than incremental lines, while the spiral sculpture is very feeble and sometimes hardly perceptible.
